Hersteller / Manufacturer
Georg Christoph and Philipp Jakob Heubach purchased the  Wilhelm Liebmann porcelain factory (founded 1822) in Lichte in 1840, and formed the new company, Gebrüder Heubach. From 1876 they started to produce decorative household porcelain, figurines, and novelties. In 1910 production included doll heads, and some beer steins. In 1919, the firm of Ernst Bohne Söhne was purchased to expand production. Success here was short-lived, operating only until 1930 and contributed to the bankruptcy of the company in 1937. 
The factory was rescued by Otto Friedrich III (b.1904-d.1990), Prince of Ysenburg and Büdingen but it was nationalised by the East German Government in 1948. 
It reverted back between 1991 & 1993, to the estate of Ysenburg and Büdingen. In 1994 the company became Lichte Porzellan, run by former employees.
The following designers either designed the pottery for Gebrüder Heubach: Ludwig Hohlwein   Adelbert Niemeyer.
